Relationships for Size and Dispersion of Pores with Mix Factors for Cement Sand Mortar
In this study the effect of age, w/c ratio on mean distribution radius and dispersion of pores in Ordinary Portland Cement (OPC) sand mortar was determined through Mercury Intrusion Porosimetry (MIP) test. For this purpose the cement sand mortar specimens were prepared from two different types of OPC with varied w/c ratios such as 0.2, 0.3, 0.4, 0.5 and 0.6 and tested at different curing ages from 1 day to 90 days. Separate relationships relating the mix parameters such as w/c ratio and age with mean distribution radius (r0.5) and coefficient (d) representing dispersion of pores, are developed for OPC sand mortars.
